* | iconv: more improvementsRon Yorston2020-02-161-55/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | - Only load required functions from mlang.dll. - The '-f' and '-t' options aren't compulsory. - Use xstrdup() instead of xstrndup() and don't check its return value. - Replace string comparisons when checking for encoding options with a single call to index_in_strings(). Saves 224 bytes.
* | iconv: code shrink (2)Ron Yorston2020-02-141-86/+34
| | | | | | | | | | | | | | | | | | Rewrite iconv_open/iconv/iconv_close to merge Windows-specific code. Make them static. Use getopt32() to process options. Saves 400 bytes.

| | | | | | | | | | | | | | Reduce the size of the codepage alias table by concatenating the alias strings rather than storing pointers to them. Saves 1328 bytes.

| * libbb: reduce the overhead of single parameter bb_error_msg() callsJames Byrne2019-07-0219-71/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Back in 2007, commit 0c97c9d43707 ("'simple' error message functions by Loic Grenie") introduced bb_simple_perror_msg() to allow for a lower overhead call to bb_perror_msg() when only a string was being printed with no parameters. This saves space for some CPU architectures because it avoids the overhead of a call to a variadic function. However there has never been a simple version of bb_error_msg(), and since 2007 many new calls to bb_perror_msg() have been added that only take a single parameter and so could have been using bb_simple_perror_message(). This changeset introduces 'simple' versions of bb_info_msg(), bb_error_msg(), bb_error_msg_and_die(), bb_herror_msg() and bb_herror_msg_and_die(), and replaces all calls that only take a single parameter, or use something like ("%s", arg), with calls to the corresponding 'simple' version. Since it is likely that single parameter calls to the variadic functions may be accidentally reintroduced in the future a new debugging config option WARN_SIMPLE_MSG has been introduced. This uses some macro magic which will cause any such calls to generate a warning, but this is turned off by default to avoid use of the unpleasant macros in normal circumstances. This is a large changeset due to the number of calls that have been replaced. The only files that contain changes other than simple substitution of function calls are libbb.h, libbb/herror_msg.c, libbb/verror_msg.c and libbb/xfuncs_printf.c. In miscutils/devfsd.c, networking/udhcp/common.h and util-linux/mdev.c additonal macros have been added for logging so that single parameter and multiple parameter logging variants exist. The amount of space saved varies considerably by architecture, and was found to be as follows (for 'defconfig' using GCC 7.4): Arm: -92 bytes MIPS: -52 bytes PPC: -1836 bytes x86_64: -938 bytes Note that for the MIPS architecture only an exception had to be made disabling the 'simple' calls for 'udhcp' (in networking/udhcp/common.h) because it made these files larger on MIPS.

| * Optionally re-introduce bb_info_msg()James Byrne2019-04-302-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Between Busybox 1.24.2 and 1.25.0 the bb_info_msg() function was eliminated and calls to it changed to be bb_error_msg(). The downside of this is that daemons now log all messages to syslog at the LOG_ERR level which makes it hard to filter errors from informational messages. This change optionally re-introduces bb_info_msg(), controlled by a new option FEATURE_SYSLOG_INFO, restores all the calls to bb_info_msg() that were removed (only in applets that set logmode to LOGMODE_SYSLOG or LOGMODE_BOTH), and also changes informational messages in ifplugd and ntpd.

* | win32: interpret absolute paths as relative to %SYSTEMDRIVE%Ron Yorston2019-03-281-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BusyBox contains hardcoded references to absolute paths which are unique in the *nix world but on Microsoft Windows are interpreted as being on the current drive. To make these unique again consider them to be relative to %SYSTEMDRIVE%. Support this by adding functions to: - determine the system drive (not using the environment variable); - change a process's current directory to the root of the system drive; - make relative paths absolute before changing directory (if needed). The following applications have been modified: - ash references /etc/profile from the system drive; - dpkg places its data store on and installs files to the system drive; - rpm installs files to the system drive; - man looks for configuration files and man pages on the system drive. See GitHub issue #158.
